use these formula.
z = (X-dash - u) / (stdev(X-dash))
Where
X ~ N(u, s^2=) and,
X-dash ~ N(u, s^2)
continue to work out the appropriate critical values for z from the tables.
Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 5.2 millimeters (mm) and a standard deviation of 0.7 mm. For a randomly found shard, find the following probabilities. (Round your answers to four decimal places.)
